Online Real-time Vibration Monitoring
The affordable channel vibration monitors from PCH Engineering measures the condition and protects the machine 24 hours a day, 365 days a year. The built in alarm function secures early knowledge of all machine faults e.g. unbalance or misalignment. This allows you to handle problems before they cause breakdowns. Most of our monitors are SIL 2 rated with MTTF(D), FIT, PFH(D) and DC diagnostic coverage numbers available.
Therefore, you can assure operational continuity of your production and avoid unplanned machinery downtime, material costs, etc.
Vibration Monitor description:
This compact, one-channel vibration monitor helps protect your plant and your machinery from unscheduled production stops and breakdowns.
The number one cause of serious machine failure and downtime is bearing damage as a result of undetected misalignment or unbalance in a machine. When the bearings of a machine are not functioning properly, the vibration level of the machine may become too high, resulting in costly machine breakdowns and production stops.
You can avoid this by fitting a PCH 1-Channel Vibration Monitor to your critical or expensive machines. The vibration monitor allows you to keep a vigilant eye on your machinery and to detect and fix any unbalance before it causes serious damage.
